WebDevelopment of the Atomic Theory. Modern Atomic Theory: Models. In 1897, J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas. Thomson realized that the accepted model of an … WebDensity functional theory modeling confirmed lowering of symmetry for the OA due to the presence of an OH vacancy and O atom in the channel formed by Ca cations. The new absorption bands at 447 and 475 cm −1 were due to vibration of the O atom in the channel in the plane of three neighboring Ca atoms (correspondingly, 470 and 490 cm −1 were …
